RINGS, SEALING, FLUOROCARBON (FKM) RUBBER High-Temperature Fluid Resistant Very Low Compression Set 70 - 80
|Publication Date:||1 January 1984|
This specification covers a high-temperature fluid resistant, very low compression set fluorocarbon (FKM) rubber in the form of molded rings.
Sealing rings for use in contact with air or a variety of fuels, lubricants, and specific hydraulic fluids from -15° to +260 0 C (-5° to +500°F). The very low compression set of these rings gives longer life than rings of other fluorocarbon rubbers, such as AMS 7278 and AMS 7280, at equal temperatures. The cross-section of such rings is usually not over 0.275 in. (7.0 mm) in nominal diameter or thickness. Standard sizes are as shown in AS 568.
